AI Technical Summary
Existing dual-tank water heaters use a lot of materials and are expensive, while single-tank water heaters cause the outlet water temperature to drop when hot and cold water are mixed, making it impossible to continuously supply hot water.
A guide riser and a baffle plate are installed in the single-chamber inner tank. The baffle plate moves up and down with the water level. The separation of hot and cold water is controlled by a valve in the guide riser. The separation and alternating supply of hot and cold water are achieved by using buoyancy and pressure difference.
By reducing material usage and costs, a continuous hot water supply is achieved in a single-tank water heater, improving hot water output efficiency and saving energy.

[0002] At present, electric water heater is still the mainstream form of household water heater, and especially the market share of storage water heater reaches 60%. The storage water heater is divided into single tank and double tank, and the performance is quite different except for the different material consumption. The single tank water heater will enter cold water at the same time when hot water is output, and the cold and hot water mixing will reduce the storage water temperature, resulting in the gradually reduced water temperature, which will cause the insufficient hot water supply when multiple people use it continuously. The double tank water heater is provided with two upper and lower storage tanks connected by a conduit. The two upper and lower tanks are heated at the same time, the upper tank outputs hot water, and the lower tank inputs cold water.

Therefore, the utility model provides a design and preparation method of single tank storage water heater with cold and hot water hollow buoyancy water separation plate, which avoids the direct mixing of cold and hot water and improves the output efficiency of hot water.
